Glass-lined pH Probes

Long-lasting and low-maintenance

pH probe type Reiner

The pH probe type Reiner in Pfaudler Hygenic Design measures pH, ORP and pH compensated ORP. The electrode’s high temperature rating, corrosion resistance and self-cleaning Pfaudler glass-lining construction make it suitable for use in the most demanding applications. The pH sensor type Reiner can be installed directly into the process without a protective cage.

The Reiner’s pressurised reference system eliminates inaccuracy and drift caused by junction potential diffusion or poisoning. The result is a more stable measurement leading to more effective and accurate process control.
